This study demonstrates the development of an ultraviolet (UV)‐C photodetector (PD) fabricated using a surface‐passivated SnO2 thin film deposited via spray pyrolysis. This PD possesses an unprecedentedly fast response speed, with both rise time and decay time of 0.3 ms. Furthermore, even when subjected to a modest UV light intensity of 6 μW cm−2, the device shows a significantly high responsivity...
Dielectric elastomers (DEs) are actively being studied to develop soft transducers including DE actuators (DEAs). Poly(dimethylsiloxane) is a popular elastomer component and known for yielding a relatively low dielectric constant (ε′) for DEAs. Herein, a novel polysiloxane‐based DE, namely, DOWSIL ME 7540 Electroactive Elastomer is reported, offering ε′ = 5.2–5.5 over a broad frequency range that...
